Review by Nine:
I saw this movie on Netflix and the I thought the title was interesting. In the beginning I first thought okay this is going to be a boring movie but after the abduction of Dae-Ho's son it got interesting.

Overall:
Keep watching it to the end, the beginning might be boring but it will get better.
